• Q: How to Service the Mass Air Flow Sensor on 2001 Ford Excursion?

  A: The service procedure for the Mass Air Flow (MAF) sensor begins by taking out the battery ground cable along with removing the engine air cleaner. Start by disconnecting MAF sensor electrical connection then remove the air cleaner clamp to split the air cleaner cavity between its inlet and outlet elements. The MAF sensing elements in the airflow meter should never be damaged because this will break down the unit. The MAF sensor needs replacement as well as its body under one fixed unit maintenance process. Proceed by taking away the MAF assembly and doing a second disconnect of the MAF sensor electrical connector before taking off the nuts which detach the MAF sensor from the MAF sensor plate. The reinstallation requires following the reversed removal steps to check that the engine air cleaner housing grommet correctly seals at the extension harness opening which stops uncontrolled engine air entry. Follow the alignment notch to correctly position the engine air cleaner inlet and outlet then position the MAF sensor wires above the sensor and its connector should face upward during reinstallation.
